IDEA:
IDEA (International Data Encryption Algorithm), formerly known as IPES
(Improved Proposed Encryption Standard).

Algorithm developed by Xuejia Lai and James L. Massey, of ETH  Zurich.
This   implementation  modified  and  derived  from  original  C  code
developed by Xuejia Lai.

Extensively optimized and restructured by Colin Plumb.

The IDEA algorithm was developed by Xuejia Lai and James L. Massey, of
ETH  Zurich.   The  implementation  used  in  Netfone was modified and
derived from original C code developed by Xuejia Lai and optimized for
speed  by  Colin Plumb <colin@nsq.gts.org>.  The IDEA[tm] block cipher
is  patented  by  Ascom-Tech  AG.   The   Swiss   patent   number   is
